To ALL WHoM TT MAY AeoNeERNz' y Be it known thatI, JUIA W. D.' P'JJTEN,of the city, county, and State of New York, have inventeda newand'improvedIce-Preserver; and I d ohereby declare that the following isa full. elear, and exact description of the construction and operationof the same, reference being had tol the accompanying drawings, making apart of this specification, in whichi Figurel is a vertical section. e v

Figure 2 is a similar section, showing anotherform of boX. v

' The obj ect of this invention is to provide a neat and cheapreceptacle, which will protect ice, food, medicines,

Xtc., from the action ofthe air; audhaving its walls made of asubstance, herein described, which is ay remarkable l non-conductor ofheat,-and will maintain around the enclosed contents of the receptacle auniform temperature,

thereby preventing the melting of the ice, and the decomposition of thefood,mcdicines, chemicals, or other v article'to be preserved.

In the drawings, A indicates a dome-shaped box orl coyer, ttingair-tight around 'and upon a detachable bottom, B, the bottom having avertical dange, b, around its rim, so as to constitute a shallow pan, inwhich the ice, iz', may be placed, and the food or otherartclesbeingplaced upon the ice, as seen at F. The-box or cover' A may beprovidedwith a handle, C, and may be'made in any other convenient form, ifpreferred, and may be ornamented at pleasure.`

Thebottom or pan B, iig. 1, is composed of tin, iron, silver, wood, 'orany other material that will be water and' air-tight. Y v l A v Thewalls and roofoil the cover A are composed of paper and pasteboard, a,on the outside lined-with mica, a', on the inside-the micalbeingattached to the paper walls by some adhesive substance, or beingstitched, riveted, or'jotherwise suitably fastened thereto. v l

The object of the paperor pasteboard is to prevent the action of theoutside air upon the ice, food, Sto., and to furnish a strongnon-conductor of heat, paper being'oueof the best known substancesfor'that purpose. The object of the mica lining is to prevent the tasteofthe food, medicines, &c., lfrom being affected by the paper or'pasteboard. Neither substance, independent of the other, Willanswer thepurpose of preserving the ice and Yother articles from the action of.the air and of heat or cold, without having their taste and' smellsensibly affected, .but combined, as described,fand employed as amaterial for the construction of covers, boxes, dto., they answer thepurpose admirably.

Ithas been found by practical test, that in a receptaclesimilar tothatshown in iig.; 1, ice will last one-third vor one-half longer than inany other ice-preserver now incommon use.

The form of the box or cover is, lof course, not a material part of theinvention. The form shown iu iig.

'1, and'herein described, is believed to be as simple, cheap, andconvenient as anyfor preserving ice in 'connection with articles of bod,butfor preserving other substances, such as dentifrices, soaps,medicines, toilet and .other perfumed articles, 36o., other forms may bemore conveniently employed, which it is unnecessary for me to describeor show.

Having thus described myinveution, what I claimas new, and desire tosecure by Letters Patent, is

An iee-preserver, consisting of a'box) or cover, Yhaving an outsidewallof paper or. p'asteboard, lined with mica. on the inside,substantiallyas described.
